No module named 'pycoral.adapters'

[arun-kumark]

Hello, I am testing the M.2 Card Google Coral on Windows10. Python version 3.8

While executing an example of Parrot, I am facing the following issue:

python examples/classify_image.py --model test_data/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite --labels test_data/inat_bird_labels.txt --input test_data/parrot.jpg
Traceback (most recent call last):
  File "examples/classify_image.py", line 36, in <module>
    from pycoral.adapters import classify
ModuleNotFoundError: No module named 'pycoral.adapters'

B'''   But the module is already present .

I am not sure , what is wrong with tmy setup, could you help?

thanks 
Kind Regards
Arun

please try uninstall tflite runtime and install from whl package from this source: https://github.com/google-coral/pycoral/releases

pip install https://github.com/google-coral/pycoral/releases/download/v1.0.1/tflite_runtime-2.5.0-cp38-cp38-win_amd64.whl

Thanks for the quick reply, I did that, but still the same output.

Below is my pip freeze output. Do you see problem?

Thanks a lot, it worked. I am not sure how it worked, but I did the installation just like you mentioned, I reinstalled (after uninstalling) and it worked. A small explanation will really helpful for future.

google@DESKTOP-QNUDFH0 /cygdrive/c/Users/google/coral $ python examples/classify_image.py --model test_data/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite --labels test_data/inat_bird_labels.txt --input test_data/parrot.jpg ----INFERENCE TIME---- Note: The first inference on Edge TPU is slow because it includes loading the model into Edge TPU memory. 11.6ms 2.5ms 2.4ms 2.5ms 2.5ms -------RESULTS-------- Ara macao (Scarlet Macaw): 0.75781

The error came because the script not able to find adapter module inside site-packages/pycoral.

Now, you can check this path /site-packages/pycoral you will find those adapter modules along with others.

Hi @arun-kumark I'd like to understand how you got into this situation. Can you please tell me the exact command you used the first time you installed pycoral?

(You ended up installing this other package called pycoral and I want to figure out how that happened so we can help others avoid it.)

I replicated on the system freshly and ended up at the same error. I am following : https://coral.ai/docs/m2/get-started/#4-run-a-model-on-the-edge-tpu Please see below my steps on Debian 11.

google@google:~$ cd coral/
google@google:~/coral$ bash examples/install_requirements.sh classify_image.py
bash: examples/install_requirements.sh: No such file or directory
google@google:~/coral$ ls
pycoral
google@google:~/coral$ cd pycoral/
google@google:~/coral/pycoral$ bash examples/install_requirements.sh classify_image.py

This looks like a different error because it says you don't have pycoral at all, whereas the original error you had was because Python could not find pycoral.adapters... Your original problem was you installed a different Python package that's also called pycoral and it does not have the adapters submodule. But now, you don't have any module named pycoral.

You can be sure to get our package by specifying the pycoral version like this:

python3 -m pip install --extra-index-url https://google-coral.github.io/py-repo/ pycoral~=2.0

But I'd still like to understand your system environment to diagnose how you got the wrong package the first time... Please run this command in a terminal and tell me the output:

python3 -c "import distutils.util;print(distutils.util.get_platform().replace('-', '_'))"
